Answer:
A'(-5, 6), B'(2, 5), C'(-2, -4). The image is <em>3 units left</em> and <em>2 units up</em> from the original.
Step-by-step explanation:
Substitute x and y into the rule to find the image coordinates.
... A: (-2-3, 4+2) = A'(-5, 6)
... B: (5-3, 3+2) = B'(2, 5)
... C: (1-3, -6+2) = C'(-2, -4)
The translation x⇒ x-3 means the point is moved 3 units to the left (in the -x direction).
The tranlation y ⇒ y+2 means the point is moved 2 units up (in the +y direction).
which means the remainder upon dividing
This is because we can write
where
